Pretty new to the forum after buying my m235i the other week. First impressions I'm over the moon with it. When buying from the bmw dealer... one of the main reasons I was interested in this particular car was because of the m performance pack including exhaust. The m perfomance exhaust was not listed on the advert however the salesman assured me that it did have it on. Even though im very happy with the exhaust note... After taking a closer look at the exhaust I was in doubt as to whether it was an M performance due to it not having the welded plate to identify it. I have included a picture and would really appreciate if somebody could confirm this.

Looks like MPerformance Chrome Tips on a standard exhaust. Part number is standard exhaust back box I believe...

The exhaust tips poke out a bit too far from the diffuser IMO.

At a guess I think the owner put the m performance diffuser on, and because it sticks out further than the standard one it covered the standard exhaust tips so instead of going for a full MP exhaust the owner bought the intermediate pipes (pipe extenders) and the MP chrome exhaust tips.
